PRQPELLlNG-GEAR FOR TRICYCLES.

SPECIFICATION forming part of Letters Patent No. 758,251, dated April26, 1904. Application filed August 14, 1903. Serial No. 169,482. (l lomodeLl To all whom it may concern.-

Be it known that I, Orro HEYNSOHN, a citizen of the United States,residing at San Carlos,

Republic of Costa Rica, have invented certain new and usefulImprovements in Propelling- Gear for Tricycles. &c., of which thefollowing is a specification.

This invention relates to propelling-gear for tricycles and other lightvehicles.

The object of the invention is to produce a hand-propelled vehicle,preferably a tricycle,

in which the power of the driver or drivers detail elevation ofmechanism connecting the i 1 compound levers.

I do not herein attempt to illustrate the frame and other old parts ofthe vehicle, as almost any usual form of tricycle or alight four-wheeledvehicle may be used.

The numeral 1 indicates the driving Wheel or Wheels, and 2 asteering-wheel, of such a Vehicle. A sprocket-Wheel 3 on thedrivingwheel or its axle is driven by a drive-chain 1 from a drivensprocket-wheel 5, as is common in vehicles of this general character.The sprocket-Wheel 5 is driven by a gear 7, engaging a pinion 6 on theaxle or otherwise in fixed connection to Wheel 5. The gear 7 ispreferably driven rotatively by an internal rocking clutch 8, havingspring-pawls 9, one or more in number, which pawls engage internalratchet-teeth 10 on thegear 7. n The rocking clutch 8 is pivoted toswing on the axle 11 of gear 7. A pitman 12 is connected to the rockingclutch by a wrist-pin 13 or otherwise. This pitman receivesreciprocating motion from a long transmitting-lever 14. The trans- Fig.2 is aside elevav mitting-lever 14 has its fulcrum on a suitable support15 near the driving gear-wheel 7. The'long arm of lever let extendsrearwardly toward the position of the operator, who may occupy seat 15.Lever 14 may conveniently extend alongside said seat. 'In the long armof lever 14 there is a slot 16. A rock-shaft crank-lever 18, which hasits arm 19 in the slot 16 of lever 14:. The rock-shaft 17 has a pinion20, rigidly attached. A geared sector 21 engages said pinion. The sector21 is rigid with hand-lever 22, and the fulcrum 23 of said hand-leverand sector is at such distance from the pinion that the gears on saidsector and pinion are in constant engagement. The rocking of lever 22backward and forward rocks shaft 17 through the geared mechanismdescribed. Rock-shaft 17 by means of its cranklever 18 causes the rearend of lever 14 to rise and fall. Through the pitman 12 and clutchgearconnected thereto the gear 7 is rotated, and this conveys rotatingmotion to the drive- Wheels through the train of mechanism described.

I have made no attempt to describe or illustrate the steering and brakemechanism of the vehicle, although such will be used. Any

usual mechanisms for such. purposes may be 7 employed.

. From the above description it is believeda person skilled in this artwill be able to make and use my invention.

The compound lever formed by the hand and transmitting levers permitsthe application of very great power-to the rotation of thedriving-wheels. When the machine is in motion, the failure of thetransmitting-lever to vibrate will not stop the machine, as thedrive-wheels may move forward and carry the clutch mechanism with them.

What I claim is 1. In a hand-propelled vehicle, the combination of ahand-lever, a sector-gear rigid therewith, a pinion engaged by saidsectorgear and rigid with a rock-shaft, a crank-lever connected to saidrock-shaft and having its crank-arm extending therefrom, atransmitting-lever having a slot into which said 1 7, suitably supportedon the vehicle, has a crank-arm extends, and mechanism actuated by thetransmitting-lever to rotate the drivewheel.

2. In a vehicle driving-gear, the combination of a longtransmittingdever, fulcrumed near the front of the vehicle, and havingdriving means leading from the front of said lever to rear drive-wheels,a crank-lever engaging a slot in the rear of said transmitting-lever tooscillate the same, and means for oscillating said crank-lever.

3. In a vehicle driving-gear, the combination of a hand-lever having asector-gear rigid therewith, a pinion engaged by said sector-gear, arock-shaft driven by said pinion and having a crank-lever connectedthereto, a transmitter-lever having a slot with which said crank-leverengages, and means by which the transmitter-lever conveys rotary motion'to the drive-wheels.

4:. In a vehicle driving-gear, a long transmitter-lever having itsfulcrum near the front of the vehicle, a pitman and a clutch connectedto said transmitter-lever and a driving-pinion actuated from saidclutch, a driving-train leading from said pinion to the reardrivingwheels of the vehicle, a hand-lever near the rear of the vehicle,and connections from said hand-lever to the transmitter-lever by whichthe same is actuated.

5. In a vehicle driving-gear, the combination of a hand-lever having asector-gear rigid therewith, a pinion engaged by said sector-gear, acrank-lever connected to said pinion, a transmitting-lever pivoted nearthe front of the vehicle and engaged by the crank of said crank-lever, apitman connected to said transmitter-lever and a clutch connected tosaid pitman, and a pinion actuated from said clutch, and drivingmechanism extending from thelast-mentioned clutch to the drive-wheels.

In testimony whereofI aflix my signature in presence of two witnesses.

OTTO HEYNSOHN.
